6.2 Typical Switching Waveforms

Switching waveforms during hard switching of the semiconductors are measured with an oscilloscope using the standard
double-pulse test procedure.

6.3 Typical DESAT Protection Performance

The functioning of the DESAT protection is obtained by performing the direct short circuit on one of the bridge legs.
